Title:
SLOTTING MILL AND CUTTING METHOD
Document Type and Number:
Japanese Patent JP2598205
Kind Code:
B2
Abstract:
PURPOSE: To raise execution accuracy by providing a control element, in such a manner as to be operated between a first position and a second position of a cutter frame by a drive device.
CONSTITUTION: Operating hydraulic oil is fed to a pair of hydraulic cylinders via a hydraulic pipe 30, and control flaps 26, 28 are expanded to fix a cutter frame 18 of a trenching mill 10 within a slot 24. The hydraulic cylinders are expanded, a signal is outputted from a strain gauge and a signal is also outputted from an inclination meter of the cutter frame 18 so that inclination of the slot 24 is measured. If inclination of the slot 24 is detected, the control flaps 26, 28 are operated so at to correct direction of the cutter frame 18, and excavation by the cutter wheel 20 is made to proceed.
